Ball Lock Ejector Punches - Light Duty, Inch, XVP Coating

Ball-lock ejector punches are used inside injection molds to deliver controlled, guided ejection with reduced risk of galling between moving components. This light-duty, inch-series variant is well-suited for molding applications where repeatability and stable punch guidance matter, but extreme core wear loads are not the primary driver.

• Automotive connector and small housing molds: The ball-lock tip provides positive retention and consistent contact during press ejection, helping maintain uniform part release when ejector forces vary across the tool.
• Appliance and fixture-based die inserts: The XVP coating improves sliding behavior and supports wear resistance, which is useful for light-duty progressive and insert tooling that sees frequent actuation.
• Precision inserts for general plastic parts: Use the inch tooling compatible shank diameter range (D = 25–100 in) and coded point length options (L = 200–600 in coded lengths) to match cavity/core layouts and ensure reliable stroke alignment.

Choose the specified material (M2 or PS4) to align with your wear vs. toughness requirements for the expected ejection cycles.

These light-duty ball-lock ejector punches are offered in two material options: M2 and PS4, supporting different performance targets depending on expected wear and tool life goals.

• M2: Typically selected when higher wear performance and ejection durability are required for repeated cycling.
• PS4: Selected when a balance of machinability and service wear resistance is preferred for light-duty mold environments.

Both variants use an XVP coating to reduce friction at the moving interface, improving sliding and helping mitigate adhesive and abrasive wear during ejector operation. Because the product metadata provides only the material grade options and coating intent, detailed heat treatment states (e.g., quenched & tempered, nitriding) and exact hardness (HRC) are not specified here; confirm the supplier’s heat-treatment data for your exact part number and tolerance requirements.

Select dimensions by matching the ejector punch to the mold cavity/core geometry and the required ejection stroke while preserving alignment in the guide system.

• Shank diameter (D): Choose from D = 25–100 in to fit the corresponding ejector bore/guide feature in your plate or fixed ejector system.
• Point length / coded length (L): Select the appropriate coded inch length based on availability for the selected series configuration. Options are listed as 200–400, 200–500, 200–600, and 225–600 (with variant-dependent subsets such as B and C coded ranges).
• Ball-lock geometry: Confirm the tip shape (H, J, K, L, N, O, R, V, X, Y, Z) and the associated Jektole group (J2, J3, J4, J6, J9) so retention and contact behavior match the mating pocket and housing.

Dimensional features such as P = 0.05–0.75 in, W = 0.05–0.437 in, and R = 0.007 in should be verified against your CAD/ejector bore drawings to maintain proper fit, avoid tip interference, and ensure consistent ejection clearance.
